Leptospirosis, caused by the pathogenic leptospires, is one of the most widespread zoonotic diseases known. Leptospirosis cases can occur either sporadically or in epidemics, Humans are susceptible to infection by a variety of serovars. These bacteria are antigenically diverse. Changes in the antigenic composition of lipopolysaccharide (LPS) are thought to account for this antigenic diversity. The presence of more than 200 recognized antigenic types (termed serovars) of pathogenic leptospires have complicated our understanding of this genus. Definitive diagnosis is suggested by isolation of the organism by culture or a positive result on the microscopic agglutination test (MAT). Only specialized laboratories perform serologic tests; hence, the decision to treat should not be delayed while waiting for the test results.
